CHELMSFORD,
Mass. – May 18, 2015 – Mercury Systems, Inc.
(NASDAQ: MRCY, www.mrcy.com), a leading high-tech
commercial provider of more affordable secure and sensor processing subsystems
powering today’s critical defense and intelligence applications, today announced the Ensemble®
RFM-1RS18 tuner. This fast-tuning wideband device is the first tuner in the
embedded industry to be developed using OpenRFM™ system building
blocks, affordably delivering comprehensive electromagnetic spectrum coverage
for electronic warfare (EW) applications.

Introduced by Mercury in August 2014, OpenRFM was
developed to solve the challenges of digital and RF/microwave convergence,
spectrum-fusion and maneuverability, complementary system interoperability, and
affordability. OpenRFM uses a modular, open-architecture approach,
standardizing the electromechanical, software, control plane and thermal
interfaces used by integrated microwave assemblies to streamline the design,
integration, and testing of RF and digital capabilities within sensor
processing systems. OpenRFM design principles are compatible with prevailing
embedded computing industry standards, including 3U and 6U form factor OpenVPX™
and VXS/VME for EW and Signals Intelligence (SIGINT) applications.

“OpenRFM’s interoperable RF/microwave and digital
building blocks enable sensor processing subsystems to be developed and
deployed more quickly,” said Charlie Hudnall, General Manager of Mercury's
Embedded Sensor Products group. “The leverage of proven IP and best
available commercial-item technology means that OpenRFM-based solutions have
high technology readiness levels and greater interoperability, making subsystem
integration smoother and solutions more robust. Additionally, the modularity of
OpenRFM building blocks enables them to be quickly deployed in a wide variety
of configurations across multiple programs and applications, which further
drives interoperability and affordability. These features allow system
integrators to quickly configure
affordable open systems-architecture-based solutions to complex EW challenges.”

The Ensemble RFM-1RS18 tuner integrates three rugged
OpenRFM modules into a single-width, 6U VXS package. Each package is comprised
of a wideband front-end tuner spanning a range of 0.5 to 18.0 GHz, a
quad-converter that delivers four IF outputs and a synthesizer to ensure
coherent outputs from the converter. Each tuner combines a high-channel
density, derived from OpenRFM’s three modules per slot approach with wide,
near-instantaneous bandwidth capability, ultra-fast tuning speed, and low-phase noise performance all within a low-SWaP
package.

Mercury Systems (Nasdaq:MRCY) is the better alternative for affordable, secure and sensor processing subsystems designed and made in the USA. Optimized for program and mission success, Mercury's solutions power a wide variety of critical defense and intelligence applications on more than 300 programs such as Aegis, Patriot, SEWIP, F-35 and Gorgon Stare. Headquartered in Chelmsford, Massachusetts, Mercury Systems is a high-tech commercial company purpose-built to meet rapidly evolving next-generation defense electronics challenges.
